Gardner Spring MB0500-025 Belleville Disc Spring

Product Description

The GARDNER SPRING MB0500-025 is a Belleville disc spring designed to deliver high axial load capacity within a compact footprint. This conical washer-style spring has an outer diameter of 0.5 inches, an inner diameter of 0.255 inches, and an overall assembled height of 0.038 inches. Constructed from steel, it is rated to handle a load of 1,190.3 pounds at its specified deflection of 0.022 inches. Belleville disc springs are commonly installed by mechanical technicians and millwrights in assemblies requiring controlled preload, vibration damping, or consistent fastener tension in tight axial spaces.

This spring is suited for use in compact mechanical assemblies where a high load must be maintained in a short spring travel. Typical applications include bolted flange connections, valve seats, bearing preload assemblies, and precision fastener stacks. Its 0.022-inch deflection range makes it appropriate for applications demanding precise, repeatable load behavior with minimal travel. The MB0500-025 is sized for use with a 1/4-inch bolt, making it a straightforward drop-in component in standard hardware configurations.

Key Features

• High load capacity of 1,190.3 pounds at 0.022 inches of deflection
• Compact geometry: 0.5 inches OD, 0.255 inches ID, 0.038 inches OAH
• Steel construction for durability in mechanical load applications
• Sized for 1/4-inch bolt applications
• Conical disc design enables high force in minimal axial space

Compatibility

Designed as an OEM-style replacement or standard-fit Belleville disc spring for mechanical assemblies requiring a 0.5-inch OD, 0.255-inch ID conical washer rated for 1/4-inch bolt hardware.

Installation Notes

Installation is typically performed by mechanical technicians, millwrights, or maintenance personnel. De-energize and depressurize the assembly before replacing any spring components. Stack orientation matters with Belleville disc springs - parallel stacking increases load capacity while series stacking increases deflection travel; confirm the required stack configuration before assembly. Follow applicable fastener torque standards per the equipment manufacturer's documentation.
